Re: what happens when 4agze knock sensor kicks in??

There is a Tech Artical on this site about the gze and it says that it knocks for about 2 seconds then retards the timing and slowly brings it back to normal.
Before I vented my intercooler properly I used to be able to hear it ping at low revs (say 50-60 in 4th) I could hear it stop but never noticed a huge power drop. I assume it would have been pinging at higher revs too (more boost, more heat, more pre-combustion) but the motor would have been too loud to hear.
Try retarding the timing, this should stop it pinging anyway without the knock sensor and see if it makes a difference.
